Problems solved by technology

In the dark state, due to the set light transmittance is single, the farther the goggles are from the weld, the less clearly the weld can be seen, and the welder can only operate at close range, which greatly limits the flexibility of the welder's operation

Embodiment 1

[0032] In this embodiment, the control module 1 adopts the SH69P56 DSP processor produced by Xinyang Technology Co., Ltd. of Taiwan, such as figure 2 As shown, its main function is that it can receive the light intensity signal from the photosensitive module 3 in real time and perform digital processing on the parameters set by the manual setting module 4, convert it into a PWM wave, and adjust it by sending out a PWM wave from the adjustment module 5. The adjustment module 5 can adjust the light transmittance of the liquid crystal lens 6 in time according to the strength of the welding arc, so as to protect the eyesight of the welding personnel and enhance the flexibility of the welding personnel's operation. figure 2 In the DSP processor SH69P56, the 9th pin is the power supply and charging control pin of the LCD lens, the 10th pin is the high-voltage charging pin, the 17th pin is the LCD power supply detection pin, and the 7th pin is the charging pin. Pins 2 and 4 are pul...

Abstract

The invention relates to an intelligent automatic dipping liquid crystal welding goggle which is based on DSP (Digital Signal Processing) control to simulate human eyes for sensitization, and comprises a control module, a light trigger module, a sensitization module, a manual setting module, an adjusting module and liquid crystal lenses. When the goggle is in use, relevant parameters of the dipping liquid crystal welding goggle are set through the manual setting module; during welding, a light intensity signal of welding arc collected by the light trigger module triggers the dipping liquid crystal welding goggle to work; and during the working process of the goggle, the sensitization module collects the intensity of the welding arc and transfers intensity information of the arc to the control module, the control module transmits a control signal to the adjusting module according to the intensity information of the arc received from the sensitization module and the parameter information set through the manual setting module, and the adjusting module adjusts the light transmittance of the liquid crystal lens according to the control signal received from the control module. The operating flexibility of welding personnel is improved simultaneously when the eyes of the welding personnel are protected.

Description

technical field [0001] The invention belongs to the field of welding equipment, and relates to a welding goggle, in particular to an intelligent automatic dimming liquid crystal welding goggle based on DSP control and simulating the light sensitivity of human eyes. Background technique [0002] During the welding process, the welding arc light is strong, which will cause great damage to the eyes of the welding personnel. Therefore, the welding personnel must wear welding goggles during the welding process to avoid the damage of the arc light to the eyes. At present, the welding goggles used by welding personnel include ordinary welding goggles and automatic darkening welding goggles: ordinary welding goggles have a single color and cannot be dimmed, so it is not convenient for welding operations when worn; and automatic darkening welding goggles can be used according to The automatic dimming of the arc light solves the problem of ordinary welding goggles to a certain extent....
